Betta brownorum

Betta brownorum (Witte and Schmidt, 1992) is a representative of the species-group coccina, which includes a total of 9 miniature species of fighting fish.

Like several other species of fighting fishes, the males are intensively coloured compared to the females. Male Betta brownorum are very aggressive to each other.

The species are distributed mostly in non-overlapping locations in south east Asia - Peninsular Malaysia, Borneo and Sumatra.

Betta brownorum occurs only in an extreme environment - the peat swamp forests of Sarawak, the Malaysian part of Borneo. Here the waters are tea-coloured and highly acidic (pH<4) but low in nutrients and dissolved oxygen.
